3 Claims.

This invention relates to lead-headed nails which broadly consist ofsteel wire nails providing integral heads to which lead is applied so asto enclose the same. One of the objects is to improve such nails so asto eliminate slipping or loosening of the lead respecting the steelheads. Other objects may be inferred.

Referring to the accompanying drawing:

Figure 1 shows the side of a nail which illustrates the presentinvention, as it appears before its head is enclosed with lead.

Figure 2 shows the top 01' this nail.

Figure 3 shows the nail after its head is enclosed with lead, the headand lead parts being sectioned.

Figure 4 shows the same as Figure 3, excepting that it is not sectioned.

. Figure 5 shows the side of another nailwhich also illustrates theinvention.

Figure 6 shows the top of the last mentioned nail.

Figures 1 through 4 show a nail including a shank I having a head 2providing recesses 3, the head being enclosed by a relatively plasticsubstance 4 such as lead, and the latter extending into therecesses 3.

It is to be particularly noted that the recesses {extend diametricallyacross the top surface of the head 2 and mutually intersect in.rightangular relationship. These recesses function to prevent slippingor loosening of the lead respectin: the-steel head.

The nail illustrated by Figures 5 and 6 includes a shank 5 having a.head 6 providing recesses I that are spaced equally around itsperiphery, this head also being enclosed by a relatively plasticsubstance 8, such as lead, and the latter ex- 5 tending into therecesses. A view of this second nail'as it appears with the leadapplied'to its head is not included by the drawing because such wouldobviously be a mere duplication of Figure 4 so far as appearances areconcerned. 10 The recesses 1 likewise function to prevent slipping orloosening of the lead respecting the steel head of this nail.

We claim:

1. A nail including a shank having a substan- 15 tially continuous andsmooth-bottomed head providing'recesses opening from its edge, said headbeing enclosed by a relatively plastic substance and the latterextending into said recesses.

'2. A-nail including a shank having a head ,pro- 20 viding recesses thatextend diametrically across its top surface and which mutually intersectin right angular relationship, said head being enclosed by a relativelyplastic substance and the latter extending into said recesses. 25

3. A nail including a shank having a. substantially continuous andsmooth-bottomed head providing recesses that are spaced equally aroundits periphery and open from its edge, said head being enclosed by arelatively plastic substance 0 and the latter extending into saidrecesses.
